Early Summer Colorado River: High Water, Morning Bites, and Solid Trout Action

Name’s Artificial Lure, checking in with your Colorado River fishing report from a local’s angle. We’re sitting on a classic early‑summer pattern. Along the upper Colorado in Colorado, streamflows are running a bit on the high side with snowmelt still easing down but dropping day by day, leaving two to three feet of visibility in most runs. The river has a slight green tint instead of full chocolate milk, which is just about perfect for trout to feel comfortable cruising the seams. No tides here in the high country, of course, but water levels are bumping a bit in the afternoon with melt and any passing showers. Mornings are your money window: cooler water, stable flows, and better bug activity. Up around the Parshall and Byers Canyon stretches, overnight lows are sliding into the 40s, with daytime highs in the 70s and light to moderate winds. Expect partly cloudy skies, with enough sun to get the midges and mayflies moving, but clouds rolling through often enough to keep fish from getting too spooky. Sunrise is just after 5:30 a.m. and sunset is a bit after 8:30 p.m., giving you a long day to work with. Best bite has been from first light until about 10 a.m., and then again from 6 p.m. to dark. Midday you’ll still pick up fish, but you’ll need to go a little deeper and a little smaller. Recent reports from local shops along the Colorado corridor between Kremmling and Glenwood Springs say anglers are into solid numbers of browns in the 12–16 inch range with the occasional 18‑plus, and plenty of rainbows in that 10–14 inch slot. A few whitefish mixed in when nymphing deep, and every now and then a bonus cutbow. Folks floating from Pumphouse down are also picking up a handful of smallmouth bass in the slower, rockier pockets as you get lower in the system. Fish activity has been strong on nymphs in the morning, with fish sliding into softer edges and tailouts. After lunch, trout are tucking tight to structure—undercut banks, boulders, and deeper slots—until shade returns. When clouds move in, you can see fish move up in the column chasing emergers and smaller dries. As for what’s working: - For trout on the upper river, the best “lures” right now are really nymph rigs: think beadhead pheasant tails, hare’s ears, and soft hackles in sizes 14–18, trailed by a midge or small mayfly nymph in 18–22. Add split shot and run them under an indicator just heavy enough to tick bottom. - Spin anglers are doing well with small **gold or copper inline spinners**, 1/8‑ounce **panther‑martin style blades**, and 1/16–1/8‑ounce **marabou jigs** in black, olive, or brown. Work those through the seams and along current breaks. - If you’re targeting the lower stretches closer to warmer water, **small crankbaits**, **2–3 inch paddle‑tail swimbaits** in natural shad or olive, and **tube jigs** around rocks are taking smallmouth and the occasional larger brown. Best bait, where legal, has been **nightcrawlers drifted on light line** through deeper runs and pools, plus **salmon eggs** or **single‑egg imitations** in slower pockets. Always check the regs—some sections of the Colorado are artificial‑only and barbless. A couple of local hot spots to put on your list: - **Pumphouse to Radium**: Classic float or hike‑in water with great structure—riffle‑run‑pool sequences, cutbanks, and bouldery seams. Excellent for browns with spinners or nymphs, and good action early and late. - **Parshall reach and Byers Canyon area**: Walk‑wade water that fishes well when flows are a little high. Focus on inside bends and soft edges behind rocks. Smaller presentations and stealth go a long way here. If you’re planning to be out there tomorrow morning, rig a two‑fly nymph setup, carry a small box of spinners and jigs, and be on the water at gray light. Work upstream methodically, cover each seam, and let the river tell you how much weight and depth you need. Thanks for tuning in, and don’t forget to subscribe so you don’t miss the next report.
